Paradox Museum Helsinki, located on Fabianinkatu, is an immersive attraction where illusions challenge your perception and sense of reality. The exhibition lets you experiment with and photograph various optical phenomena. We recommend setting aside about 45–60 minutes for your visit, and you’ll select your entry time when purchasing your ticket. Children under 13 must be accompanied by an adult. This attraction is ideal as a shared urban experience for families or groups. Any extensions to school vacation periods will be confirmed separately.
